Hi ChiLian and Robert, Thanks ChiLan, your EOT curve is interesting. I suppose anything to do with sundials has a high chance of being invented before as sundials have been around for a long time.
Robert, the kidney shape cam in the watch is interesting, is this watch still in production and can it be purchased. I’ve never seen a watch with EOT indication. Thanks, Roderick Wall.

Here is a picture of the gear carrying the kidney piece. It turns once a year. http://people.timezone.com/mdisher/decorte/gyro2/gyro2_3.jpg Bob -------------------------------------------------------------------------------- From: sundial-boun...@uni-koeln.de [mailto:sundial-boun...@uni-koeln.de] On Behalf Of Chiu ?,Chi lian Sent: Tuesday, June 21, 2011 12:11 PM To: sundial@uni-koeln.de Subject: EoT diagram Hi, I figured out a way to plot EoT curve which I didn't see in sundial books I own.
